Java is a general-purpose programming language that is class-based, object-oriented, and designed to have as few implementation dependencies as possible. It is intended to let application developers write once, run anywhere (wora),meaning that compiled java code can run on all platforms that support java without the need for recompilation.java applications are typically compiled to bytecode that can run on any java virtual machine (jvm) regardless of the underlying computer architecture. the syntax of java is similar to c and c++, but it has fewer low-level facilities .
one design goal of java is portability, which means that programs written for the Java platform must run similarly on any combination of hardware and operating system with adequate run time support. This is achieved by compiling the Java language code to an intermediate representation called java bytecode, instead of directly to architecture-specific machine code. java bytecode instructions are analogous to machine code, but they are intended to be executed by a virtual machine (vm) written specifically for the host hardware. end users commonly use a java runtime environment (jre) installed on their machine for standalone java applications, or in a web browser for java applets.
